Even though FreeBSD 7.x is already out and updated, the FreeBSD team keeps working on the FreeBSD 6.x branch, now designated the legacy branch. They released FreeBSD 6.4 today, with lots of new features, fixes, and updates. They are expecting FreeBSD 6.4 to be the last release in the 6.x branch.

The highlights of the release are listed as follows:

New and much-improved NFS Lock Manager (NLM) client

Support for the Camellia cipher

boot loader changes allow, among other things, booting from USB devices and booting from GPT-labeled devices with GPT-enabled BIOSes

DVD install ISO images for amd64/i386

KDE updated to 3.5.10, GNOME updated to 2.22.3

Updates for BIND, sendmail, OpenPAM, and others

The complete release notes are of course also available, as is the errata list. This release is supposed to be supported by the security team until November 30th, 2010. Using torrents for downloading this release is usually preferred, but you can of course also check your local mirror.
